This is consistent with findings for nearly two years. A higher percentage of voters have consistently blamed global warming on planetary trends rather than human activity since early February 2009 despite the insistence of President Obama, the United Nations and a large part of the world scientific community that humans are the bigger culprits.

Regardless of what’s to blame, voters take global warming seriously. Fifty-nine percent (59%) say it is at least a somewhat serious problem, including 32% who see it as Very Serious. But this concern has fallen since last November when the so-called ‘Climategate’ scandal broke, raising questions about the reliability of pro-global warming research. Thirty-eight percent (38%) now do not see global warming as a serious problem, including 16% who say it’s Not At All Serious.
